and Sil iimn ESFOUTS, 'citize'ns of the United States,lresiding at Alliance and East Cleve. land, respectively, in the counties of Stark and Cuyahoga, respectively, and State of Ohio, have'invented a certain. new and useful Improvement in Accounting and Filing Apparatua'ot' which the following is a full,

clear, and exact description, reference being hadto the accompanying drawings.

This invention relates to combined adding or registering mechanism and filing appliancesflandit' has particular reference to an adding device'that'is adapted to be attached to afmachine tha'tis'knownas The McCaskey Account Register, one example of said machine being illustrated in the patent granted to 'P.'A. McCaskey, No. 783,126, Feb.'21,l905, to which patent reference is here made for a specific disclosure. of said machine; In" general, however, it may be stated that 'sald chine is intended to take care ofaccounts" in business houses, and

consists of a series of leaves pivoted at their lower edges, 'saidleaves having a series of clips'behind,which t-he accounts oi customers are kept, eachJ-customer havin a clip appropriatedto h's use. As is's own in said patent, the front leaf of the'series serves as a cover for theremaining leaves. In our invention, we'utilizethis coverplate or leaf as a lever towhich power is applied for operating the adding attachment or mechanismi In the machine as now constructed,

there are no means for adding the amounts of thecredit accounts, and the proprietor can determine'the total amount of such accounts OnlyJby the laborious process of taking. thewvarious slips or checks held by the numerous clips'and adding them with penoil and paper. This, of course, requires considerable time and trouble, and'is attended with the usual number of mistakes incident to such a process. Our machine is intended to keep a continuous registration of all these accounts, and the proprietor can determine at any time the amountthereof by a simple reference to his adding wheels.

Our invention also provides means for locking the cover plate until a key in the i bank o ey r until the e No @AcooUN'rINsr AN FILING APPARATUS.

F or 'further description, reference will now be made to the drawings, in which similar reference characters designate corresponding parts throughout the several Views, and in which 1 represents the casing, preferably of the typeused in the ,ordinary McCaskey register or filing appliance, in the upper part of which is contained the leaves 2, for carrying the account slips. These slips are held on the leaves by suitable spring clips 3, one example thereof being clearly set forth in the McCaskey patent above. referred to. .4; is the cover plate for saidleaves 2. The cover plate is pivoted at its lower edge as shown at 5, and is preferably pressed toward its closed position by the springs 6, that are coiled in line with the pivot of the plate and bear with one end against the plate and with the other against'a stationary part of the frame. As has been stated, and as is described in the patent referred to, all the leaves with the cover plate are preferably detachably mounted in. the frame of the machine, and may be disconnected therefrom and placed in a vault for safe keeping.

Secured to the interior of the casing at each end, and preferably set within a ra beted portion of said casing, jareplates 7. Said plates may be of the contour shown in Fig. 2. Projecting inwardly from these plates, coaXially with the pivots of the cover plate 4, are cylindrical lugs 9, said lugs forming a bearing for toothed operating segments 10. These operating segments are adapted to be detachably connected to theside edges of the cover plate, so that, when said plate. is moved in opening or closing,

the segments will be swung'upon the lugs 9.-

In order to attach the cover plate'to the segments, the latter are extended upwardly in theform of an arm 11, said arm being, in section, shaped like a channel iron. (See Fig. 18.) That is to say, it hasa central portion perpendicular to the plane of the cover late. and a flan e on each ed e said flanges being parallel to the cover plate. Mounted to slide longitudinally within the channels of these arms are clamping plates 12, said clamping plates being also shaped like channel irons, the plates being adapted to receive the edges of the cover plate within the said channels. Preferably, the chan- I nels are V-shaped, in order that they may secure a firmer hold upon the cover plate. The flanges of the arms 11 are provided near their upper and lower ends with L shaped cam slots 13, said slots having their shorter ends extending in a substantially vertical direction and their longer ends inclined downwardly and inwardly: The clamping plates are provided with pins 14, that project into the cam slots 13, by means of which the said plates are supported and guided. The ,clanfping plates are also provided .with lifting knobs or buttons 15, upon which the operator can lift so as to engage or disemgage the-clamping plates from the edges of the cover plate. Preferably, the jaws of theclamping plates arelined with, rubber or loo other non-abrasive material 16, so that they will not mar the cover plate. From this description it will-be understood that when the parts are in engaging posltion, as shown in Figs. 3 and 3, they may be. disengaged by simply lifting on the knobs 15 of the clamping plates, which plates will thereupon be lifted and cammed backwardly by the slots 13 until the cover plate is disengaged. By releasing the knobs the clamping plates will then drop with their pins 1 f resting in the short arms of the cam slots; and, while so positioned, the plates 12 will be maintained out of operative relation with the cover plate, and the latter with all the leaves maybe taken from the machine. When these parts are to be again placed in the machine, the cover plate is clamped tothe operating. segment arm by simply lifting the clamping plates until their pins canenter the longer arms of the cam slots, when,

by forcing the plates downwardly, they will securely grip the edges of the cover plate.

By extending the clamping plates for a con siderable distance along the edges of the cover plate, the latter is strengthened and danger of buckling is obviated.

Those parts of the operating segments 10 i that are below the pivots project throu h slots 17 in the upper part of the'casing, and

emmas segments and gears are held in position on.

the lugs of this plate by means of washers 19, said washers being secured to the lugs by screws 20 which pass through the washers and into the lugs.

I unlock the cover plate.

The parts .on the two sides of the machine are identical. except that one set is right:

hand, the other left hand, and a description of one set willsuffice for both. I

The gear 181 is provided with teeth extendmg aboutits periphery, except at 2-1, Where it is blank. There are sufficient teeth, however, to permit a full swing of the segment and cover plate. At 22 the disk is provided with a catch or lug. with which engages a locking lever 23, said lever being secured to a rock shaft 245 that is mounted in the rear of the'casing. To one of the locking levers there is pivotally secured the rear end of a bar 25, the forward endof which is connected to mechanism under control of the keys in the cents bank and the No sale key, as will be hereinafter described, so that,

when one of these keys is depressed, the look ing levers will be simultaneously rocked to In order to secure perfect parallelism of movement of the parts at the two sides of the casing, pinions 26 are caused to mesh with the teeth on the.

Springs 32 bear upon the upper flat portions of the pawls and hold the same normally in the position shown in Fig. 2, in which position it is beyond the rear end of the row of ratchet teeth. When the cover plate is turned down, the ratchet teeth push the lower end of the pawl into an inclined position; and while in such position the pawl will resist any backward movement of the segment by engaging 'the teeth of the ratchet. until the pawl has passed over the forward end of the row of ratchet teeth, when the pawl will again take a vertical position. Upon the return of the cover plate the pawl is again inclined, and will effectuallv resist an reversal of movement of the coter plate until the same has been closed.

' By this means, the cover plate is compelled to swine through an angle that is sufficient to caus the parts of'the registerlo operate 'n'operly.

The gear wheels 18 are each provided on and carry at their lower e fds 'anti-friction rollers 35 thatjworkbetweemfingers 36 and 33, which travels in a cam slot 34 in the corresponding operating lever 29.: Below the cam slots, these levers extend downwardly 37 on the rear end of arack frame, hereinafter described. I v

With the parts in the position shown in Fig. 2, the roller 33 is near the upper end of the cam slot 34:, and is slightly to'oneside of the line drawn vertically through the cen- ,ter of the gear wheel. 4 As the cover plate is opened, the roller pushes'the leverrearwardly, carrying the rack frame with it. When the roller reachesthe position shown in broken lines, the rackframe has moved its full extent. Consequently, the cam slot is made in such a shape that, with the leyeiw, in this position, said slot will be'concentric with the journal of the wheel. Any further" movement of the wheel, therefore, will have no effect on the rack frame. It will thus be seen that the rack frame ismoved rearwardly during the first part of the opening movement, of the cover. plate,- and is not returned until the last part of the jclosing movement of said plate. ,The purpose of this mode of operation will be made to'appear hereinafter.

The rack frame is offopen rectangular form, consisting of the side bai's38, the rear cross bar 39. and the front crossbar 40/ The fingers '36 and 37 project upwardly from the rear ends of the side bars 38.. As the side bars 38 are moved simultaneously by the op: erating levers 29 and are brace'd together by th cross bars, all danger of binding or twisting -is avoided. I

Near their front ends, the side bars fare each provided with rack teeth 41, which teeth mesh with pinions 4E2 onfatransverse shaft 43, said pinion beingkeyedor otherwise secured to said shaft. A s 'the rack frame is moved back and fgrth. the shaft 43 will be turned, first in one?direction" and then in the other. ,Thesize of the piiiions 42 is such that the shaft will beturiie'd a trifle more than a complete rotation with each complete stroke of the rack frame. Also keyed, or otherwise secured, arena shaft are gears 44:, there'bing one of said gears for each orderof'keys in thekeybank.

The registering mechanism proper "coir. tainedwithin a casing to that is"attach ed in any suitable manner tolthe front of the main casing 1. Passingthrough the register casing near its center, is a main supporting shaft 46. said shaft being supported at its ends in brackets d7 that are secured 125 within. the registerfcasing. f Supported loosely upon this shaft, are a series of key drums. one foreach order of keys in the key bank, the cents drum beingdesignated 48, the dimes drunuaf), thedpllars'dru ii 50, 139

these gears and the tens of dollarsdrum 51. One of these drums is shown in perspective in Fig. 12, with parts broken away to show the interior construction, and from this view,

' taken in connection with Fig. 4, it will be seen that the drums consist of a shell with a pair of inwardly projecting journal flanges, 52 and 53, the flange 53 being at one end of the drum and the flange 52 being removed some distance from the opposite end thereof, for a purpose hereinafter set forth. The journal flanges for the drums do not bear directly upon the shaft 46, but, in the case of the drums 48 and 51, they are secured to sleeves 54 and 55 respectively, while the drums 49 and 50 turn loosely upon said respective sleeves.

Carried loosely upon the shaft 46 are gears 56 and 57; and similar gears 58 and 59 turn loosely upon the sleeves 54 and 55. Each of mesh and turn with the gears 44011 the shaft 43, so that they oscillate back and forth with the movements of the rack frame. The gears 56 to 59 are each placed at that end of the corresponding key drum that has the journal flange 52; and they are connected yieldingly with said flanges by coiled springs 60, said springs being attached at one of their ends to a gear and at their other ends to a flange 52, the flange being set inwardly fro-m the end of the drum to accommodate the spring. Each of the gears 56 to 59 is provided on its side next its corresponding drum' with a pin or projection 61, that is adapted to engage with an inwardly extending plate or projection 62 on the drum, the tension of the spring normally holding-these projections .in en gagement, the drums tending to follow the wheels in their oscillatory movements.

Opposite each of the drums 48 to 51, and projecting through the casing 45 in a direction substantially radial with respectto the shaft 46, are a series of value keys, the cents keys being shown at 63, the dimes keys at 64, the dollars keys at 65 and the tens of dollars keys at 66. Each of the said drums is also provided with aseries of projections 67 on its outer surface, said projections being adapted to be intercepted by the ends of the keys when in-depressed position, each lug having its own appropriate key and the keys and projections being so arranged that the No. 9 key in each bank will permit the drum in .said bank to move nine times as far as it will when the No. 1 key in that bank isdepressed. Normally. the keys are projected radially so as to lie outside the orbits of said projections; but when the keys are depressed to their, full extent they will project within said orbits and will in tercept said projections and thereby arrest the rotation of the drums. As shown, each of the different orders has nine keys except the cents order, which is provided with a 'pressed positions by zero key in addition, .for a purpose hereinafter set forth.. "1

The keys are preferably guided in their movements by the casing 45 and by interior plates 68 attached to said casing, said plates being spaced from the casing so as to more effectually guide the keys and to provide a space for the coiled springs 69, which surround the key stems and bear with one of their ends against the plates 68 and with their other ends against pins 70 that are These pins passed through the key stems.

which serve as abutments for the spring, normally hold the keys outwardly.

From Fig. 10 it ,will be seen that the keys are each provided with squared stems 71, and rounded heads or captions 72, upon which head the appropriate figure designating the value of the key can be placed. The lower ends of the keys are beveled in one direction at 7 3, said bevel being continuous with the bevel on the lower edge of lugs 74 that project from the keys near their lower ends. These lugs normally rest inner face of the plate 68, and thereby serve to prevent the keys from being forced too far outwardly by their springs 69. They also serve tov hold the keys in their deplates, now to be described. a As the keys do not actuate the registering mechanism, but merely determine the extent of operation thereof when the cover plate is moved, it is obvious that some means must be provided for holding the keys in their depressed positions while the cover plate is moving. These means consist, primarily, of a series of detent plates, one of said plates being shown in perspective in Fig. 13. The detent plate for the cents keys is designated 75; that for the dimes keys, 76; that for the dollars keys, 77 and that for the tens of dollars keys, 78. These detents consist of a central plate 79, said plate being turned at right angles at its ends to form a yoke. The ends of said yokes are provided with j ournaled bosses 81, through which openings are formed so that the detent plates can be mounted on the shaft 46, or the sleeves 54 and thereon. As will be seen from Fig. 4, these detent plates or yokes straddle their respective key drums, and the central plates 79 are curved so as to be concentricthroughout the greater part of their widths with the shaft 46. The detent plates are'feach proagainst the engaging with detent tent plates. Referring to Fig. 6, it will be seen that as the cross bar 40 moves rear- The perforations are elongated, as shown in .Fig., 13,. so as to permit the detent plates .to sw ng about the shaft 46; and, when the .keys are depressed, the beveled-portions of the keys-and the lugs 74 thereon cam the the plates rearwardly against the tension of the springs '83, the elongated perforations permitting this movement. As soon as the lug 74'l1as passed beyond its detent plate, the latter is swung forwardly by its spring 83 and engagesaloove the lug, which holds the key depressed with its inner end inthe path of the corresponding projection 67.

. At substantially the end of the operation of the machine, the keys must be released. ThlS result is accomplished by the rack frame cross-bar 40, which engages with depending by-p-asspawls 84 that are pivoted on the forward ends of arms 85 that-project from one of the journal bosses 81 of the depwardly with the opening movement of the -.cover plate, the pawls 84 simply rock on their pivots without moving the detent plates; but, on the return movement of said cross bar,'the pawls will act as rigid parts of the arms 85, due tothe engagement of the upper ends of the pawls with stationary lugs86 on said arms, and the detent. plates will be lifted to release the keys, which then spring outwardly. Before coming to rest, the crossbar passes the ends of the pawls .84, and the detentplates are then brought back to theirnormal positions by their springs 83. While the machine shown is adapted to aregister amo unts at a single operation vary- 'lngfrom one cent up to $99.99, 1t. 1s ob- :vious that the capacity of th ekey board may befenlarged by simply addmg'other orders 0f keys to the left. hand end thereof, or it may be diminished as desired.

e-will now proceed to describe the regisa a series of adding wheels, the cents wheel tering mechanism proper. This consists of being shown at 87, the dimes wheel at 88, uthedollars wheel at"89, the tens of dollars -.wl1eel at 90 and the hundreds of dollars wheel at 91. These wheels are all mounted on the central shaft 46, except the wheel 91,

- said sleeve.

5 92 is connected to the sleeve, these parts must 6 "which is loosely mounted on the sleeve 55. -The wheel, 87. whlch is shown in enlarged side elevation in F1g. 7, is operated from the 55 cents drum 48. through the mediumof the a sleeve 54, said wheel being at the end of Pinned, or otherwise secured to the end of said sleeve next the wheel 87, is 'a. ratchetwheel 92, having teeth on its outer periphery with which is adapted to engage a pawl 93'that carried on the side of the wheel 87.

As the sleeve is connected to the cents key drum and the ratchet wheel movetogether,:tlie ratchet wheel oscillating back and forth with the drum. When mjov ing-to the right, in Fig. 7, the pawl engage theteeth ofthe ratchet wheel and cause the adding Wheel 87 to turn there-' with; but when the ratchet wheel moves in the opposite direction, the pawl will trip over theteeth without moving the adding 7 wheel, said wheel being held against backward movement by a suitable detent pawl,

not shown, that engages with ratchet teeth 941- on the outer-periphery ofsaid wheel.

The outer rim of the adding wheel over} hangs the ratchet wheel and pawl so 'asto i provide a surface sufficient for carrying the w numerals 0 to 9,v the ratchet teeth Mand'aj transfer lug 95, whichwill be morespecifi cally described hereinafter. The dimesadd ing wheel 88 derives its motion from-the;

dimes key drum 49-; and to provide for such" movement, We attach to the end of said key drum, as by screws96, a gear wheel 97, said gear wheel meshing wlth a pinion 98 secured Y to one end of a short shaft 99, that is-journaled in a bracket 100, suitably supported from the base of the casing. On e opposite I end of the shaft is similarly secured a pinion 101 which meshes with a combination gear 1 I and ratchet wheel 102 onthe main shaft 46 alongside the tens adding wheel-88; The ratchet'of this wheel is carried on an annular flange-1'03 that projects toward its adding wheel so as to-be engaged by a pawl on saidwheel like the pawl 93 on thecents' wheel. The pinions 98 and 101 are of the same size, as are also the gears 97 and'102, so that the adding wheel' 88 is turnedprecisel'y hat the same angular distance as is thevkeyw drum 49. f This adding wheelfaszwellas all of the remaining adding wheelsenc'ept the last, is also providedwith-a ratchet ring 94,

that meshes with a pinion 105 on one end of; (y

a sleeve 106 that is journaled on a stud bolt 107, said bolt being supported from abracket 108, suitablysupported from the ba'se-of-the casing. On the opposite end of this sleeve is a pinion 109 that meshes with. another-.3.

- being one of these projections for each ad secured to the side of the adding wheel and Y engaging the ratchet wheel, in the same manner as has been described in connection with the cent-s adding wheel.

The hundreds of dollars adding wheel has no corresponding key drum shown, but it derives its movement solely through tie trans ferring mechanism.

Carried upon the shaft 4C3, at the rear of and below the adding wheels and ietween brackets 112 and 113, are a transfer camsleeve 11 1 and a pawl carrying arrn 115. The cam-sleeve is loose upon the shaft, while the arm 115 is secured to the shaft and swings back and forth as the shaft oscillates. This arm carries a pawl 116, Fig. 8, that is adapted to engage'with a lug 117 near the A suitable spring will be employed for holding the pawl into engagement with the sleeve, so that it will strike the lug 117 and turn the sleeve with it in one direction, but will trip over thelug and leave the sleeve stationary as the pawl moves backwardly. As will hereinafter appear, it is necessary for the cam-sleeve to be given one complete rotation at each operation of the machine; and it has already been stated that the shaft 48 is given a trifle more than a complete rotation with each full stroke of the rack frame. This excess of movement over the complete rotation is for the purpose of assuring the proper engagement of the pawl 116 with the lug 117. The cam-sleeve is prevented from moving backwardly with the pawl by a catch 118 that is st'ationarily mounted in the casing, said catch engaging with a ratchet wheel Arranged spirally about the cam-sleeve 111 are a series of cam projections 120, there ing wheel except the one of highest denomination. Mounted on suitable supports'121, arising from the casing in front of the camsleeve, are transfer levers 122, said levers being pivoted near their rear ends and provided on said ends with anti-friction rollers 1213. These rollers are adapted to be engaged by the cams 120 as the sleeve 11a is turned. On their opposite ends these levers carry pawls 124: for engaging with the ratchet teeth 91 of the adding wheels, said pawls being pressed into engagement with said teeth by springs 125. On their sides next the adding wheels and just in front of their pivots, these levers are provided-,with cam-lugs 126, said lugs lying in thesame planes as the lugs 95 on the adding wheels. Fi 5 shows the transfer levers 122 and also the ratchet teeth 94: on the adding wheels, and from this figure, it will be seen that each of the levers is bent laterally, so that, while its cam lug 126 lies in the plane of the orbit of a-lug 95 of one adding wheel, its pawl 121 taneously from the plates 62 on their respec- -wheel corresponding .cover plate is closed,

is in position to engage with the ratchet teeth of the adding wheel of the next higher denomination. From this description it will be understood that, as'the lug 95 on one adding wheel passes the cam-lug 126 appro: priate thereto, the lever-122 having-said lug will be depressed to' carry its pawl 124 downw'ardly farenough to cause it to move over one tootlr of the ratchet'wheel of the next higher order and take a position for engaging with said tooth. Thereaftenwhen the cam-sleeve is rotated, the cam 120 thereon will force the rear end of the transfer lever downwardly and throw up the forward en of said lever, which will cause the pawl to turn the next adding wheel the distance of one tooth, thereby adding one on said wheel. There is a transfer lever and a transfer lug 95 for each adding wheel, except the one of highest denomination; but, as these levers are alike in construction and operation, itis not deemed necessary to'describe them further, except to state that, owing to the spiral arrangement of the cams 120 on the camsleeve, the levers will be operated successively.

In order to hold the transfer levers in either their upper or lower positions, they are provided with lugs 127 below their pivots, with which engage plunger bolts 128, said bolts being pressed toward the lugs by s )rings 129. The upper end of each bolt is rounded, as shown, so as to engage with either face of the adjacent lug, and thereby hold the-levers 122 yieldingly in either of their two positions.

From the description heretofore given of the operating mechanism it will be understood that, as the cover plate moves forwardly in opening, the rack frame will move rearwardly. This, through the connecting train of gearing, will cause the gear wheels 56, 57, 58 and 59 to turn simulin a direction to carry their pins 61 away tive drums. The tension on the springs 60 is sufficient, however, to cause the drums to follow the gears, and the pins and plates are maintained in contact until the drums are arrested by the keys that have been 'depressed, when the pins'and plates separate, the springs being then'f' put under stronger tension. The gears 4A proportioned that the trifle more than one rotation of the former will turn the latter gears only about nine tenths of a revolution, since the drums should never rotate farther than is necessary to add 9 onthe adding thereto. When the the gears 56 to 59 are rotated in a reverse direction to their initial movement; and, during such reverse movement, the drumsare picked up and also returned to normal position. The teeth on the ratchets 92 and the pawls 93 on the addingwheel s are so. arranged that the said for the key drums,

and 56 to 59 are so I fl is adapted to pheels are turned to add'the value of the de keys during the opening movement the cover plate; and the pawl 116 is ar- 1 :{iangPdto turn the cam-sleeve 1. l to efiect ftlie transfers during the closing movement of the cover plate. In fact, the ":ack framev "is moved to permit the adding wh Eels to turn to add during the first part of 1e opening movement of the cover plate, while the camsleeve is not turneduntil the last part of the closing movement of said plate. By this construction, amplev time is afforded for the 'key drums to turn to the positions determined by th. depressed keys before they are I '15 picked up ag. in by the pins 61. i

- B a SlIIlP'-3 reversal of the ratchets and :paw s for turning the adding wheels, and of the pawl for turning the cam-sleeve 114, the

i nachine may be caused to add during the 'closin movement of the cover plate, and. to

. trans er during the next opening movement thereof. This manner of operation causes the adding wheels to be turned positively,

;;' but it has the disadvantage of postponing 1' 5 the transfer until the next operation of the machine.

' Means must be provided for preventing the key drums from turning except when a 1 key in the order corresponding thereto has 0 been depressed. Otherwise the drums would cause their adding wheels to register 9 with each operation of the machine. This means consists of a series of hooks or pawls 130,. Fig. 6, which are normally engaged withone of'the projections 67, or with a sepat ite-lug on the drums, said hooks being '-;p ;essed by springs 131 into engaging posiftion. There is one of these plates for each key drum, or for each detent plate, and they 40- 'ardcontrolled by said detent plates. For this purpose, each hook is provided with a forwardly projecting lug 132 just at the rear edge of the corresponding detent plate; and when said plate is moved rearwardly .545 iby the depression of a key in the order cor responding thereto, the hook will be disenfgaged from its lug 67 so that the drum may urni's the cover plate is opened. It will be understood that when no key is depressed in an order of keys, the corresponding dejtent plate willjnot be moved, and conse- "quently, the key drum of that order will "re'main locked.

3 After any key in the key board has been 555 depressed and held by its detent, it can be released at any time before the cover plate is moved by simply depressing another key in "the same order, the second key moving h the dete'ht plate far enough to free the first.

After the cover plate has been moved, however, all "the keys should be locked against I movement.

For this purpose we provide a yoke shown in perspective in Fig. 11 which be moved rearwardly into engagement with the detent plate so that they bars 38 of the rack frame.

side of all'the detent plates. The cross bar 133 is provided with ase'rie's of fingers 135 that project forwardly at the rear. of the de-- tent plates. By swinging this yoke forwardly, the fingers will engage with the detentplates and prevent themovement thereof, which will prevent the depression of any 21 other keys, and will holdfthe depressed keys in locked position. Theyoke is thus swung by means of arms 136, depending from the yoke and carrying on their lower ends antifriction rollers 137, said'ro-llers bearing upon cam plates 138 on the inner sides of the side I Fig. '6 showsthese parts in normal position; and, from this figure, it will be seen that, as soon as the rack frame is moved 'rearwardly, the yoke will be cammed forwardly and held in this position until the cover plate and the rack frame have substantially resumed their normal ositions. It is also desirable to prevent t e movement of the cover plate unless a key bank has been depressed. For this purpose the locking lever23, heretofo'redescribed, is employed. The bar 25 connected to said lever extends forwardly, as shown in Fig. 6, and enters the casing for the registering mechanism where it is pivoted to the lower end of a swinging arm 139 that is pivoted to the upper part of the casing 45 at 140. This bar has connectedtto it, at a point 141, a horizontal link 142 that projects forwardly to a'point just at the rear of one of the detent plates, the said link being held in proper relation with the detent plate by a link 143, also pivoted to the upper part of the casing 45 and to the link 142 in front of the point 141.. W hen a key belongin to that detent plate is depressed,

said plate will force the link 142, the arm 139 and the locking levers 23 rearivardly, thereby carrying the latter out of engaging position with respect to the catches or lugs 22 on the gears 18. The cover plate can then be opened.

While the machine may thus be unlocked from any key in the key bank, we prefer to operate the unlocking device entirely from the detent plate 75 of the cents order, it being obvious that most transactions will involve the depression of akey in that order and that the natural order of depressing the keys will be from the tens of dollars on down to cents. By simplychanging the location of the link 142, or by duplicating the same, we may unlock the machine by depressing any key in the key board. v It is'sometimes necessary to refer to the 'we have placed in the cents order;-*as*is the hub of each adding wheel.

ing to said cents key drum. This would permltthe drum to rotate with the opening movement of the cover plate if it did not otherwise hold the'drum, which it does by entering the perforation 146 therein.

A appears from Fig. 1, the casing 45 for the registering mechanism 18 made in two parts, separated by a section 147 of the easing which covers the adding wheels. This section is lower than the adjoining parts of the casing, which enables the register wheels to be more easily inspected, the said section being provided with openings 148 oppositethe adding wheels and through which the amgunts indicated'by said wheels may be rea It is desirable at the beginning of a days business to start in with a new registration; and, for this reason, we have provided means for turning the register wheels back to zero. As has been stated, the register wheels are journaled on the central'shaft 46. Opposite the adding wheels the shaft is provided with sockets 149, in which are placed plungers 150, said plungers being pressed outwardly by springs 151 in the sockets below the plungers. These plungers are adapted to'engage with a notch 152 in the interior of By this means, a rotation of the shaft 46 in the proper direction will carry the adding wheels around with the shaft until they will indicate zero through the openings 148. In

order that the shaft may be rotated, we extend the same through the casing at one end, where it is provided with holes 153 for the reception of a suitably shaped key, not shown, bv means of which the shaft may be rotated. In order to hold the shaft from longitudinal movement we form the same with an annular groove 154 near one end, into which projects the end of a set screw 155 that is screwed intothe bearing of the bracket 47 1 \Ve have also provided a device for sounding an alarm when the cover plate 4 is opened, said device being shown particularly in Figs. 3 and 20. This device comprises a bell 156 and a clapper or striker 157 that is secured to the lower end of a flexible wire or rod 158. This rod is secured to the lower end of a flexible plate 159 that is secured at its upper end to the casing. laterally projectinglug 160 near its lower end that extends into the path of movement The plate has a of'a tripping finger 161 that projects upwardly from the cross bar 29 of therack frame. This finger is pivoted to the cross bar in the manner of a knife-blade, so that it will turn in one direction against the, tension of 'a spring 162, but will stand rigidly against pivotal movement in the opposite direction.

As the rack frame moves rearwardly upon the opening movement of the cover plate, the finger 161 swings the clapper, bending the plate. 159; and, when the finger passes the lug 160, the plate springs forwardly, ringing the bell. 'When the rack frame moves forwardly, the finger rocks upon its pivot and passes the lug without bending the plate 159.

In order to provide 'an adjustment for the rack frame so as to cause the front bar 40 thereof to release the keys at the proper time, we divide the side bars 38, as shown in Fig. 21, and secure the members of the same by screws, which pass through slots 163 in one of the members. By loosening these screws, the length of the side bars may be varied, and such length maintainedby again tightening the screws.
